Chirality and its importance in environmental organic analysis
Svobodová, Dagmar ; Friedl, Zdeněk (referee) ; Čáslavský, Josef (advisor)
This bachelor thesis is elaborated as literature search focused on the characterization of chirality and its importance for the environment. This work also gives review of the analytical methods and procedures aplicable for the chiral analysis of the organic pollutants. Obtained information showed that the importance of the chirality in the environmental chemistry is great. Individual enantiomers exhibit different toxicity and biological activity in the environment and therefore their monitoring by chiral analytical methods is essential.

Palladium in the environment
Hajdová, Jana ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
This work is focused on palladium in the environment. Its use is especially in the automobile industry as catalytic converters of motor vehicles, but also is applied in dental, jewelry making and electrical appliances. The release of this metal from automobile catalysts is getting into all environmental compartments (soil, road dust, water, plants), where goes to its accumulation. It can be a part of the food chain and cause health risks to humans. The work also focuses on methods of sampling, preconcentration and methods, which can determined palladium in environmental samples (spectrophotometric methods, AAS, ICP-AES and ICP-MS).

Rhodium in the environment
Ondreášová, Klára ; Nevrlá, Jana (referee) ; Komendová, Renata (advisor)
This bachelor thesis focuses on the characteristic of rhodium, its use in the automotive industry, the occurrence in environmental compartments (air, soil, vegetation, water), accumulation and transformations. In this thesis there are also described methods of sampling for determination, the types of sample preparation, separation and preconcentration techniques necessary prior to instrumental analysis. The work also focuses on the most commonly used analytical methods of rhodium determination, which are spectrophotometric methods, AAS, ICP-AES and ICP-MS.

Environmental Aspects of Pyrotechnic Mixtures.
Mešková, Michala ; Bednařík, Karel (referee) ; Friedl, Zdeněk (advisor)
The submitted bachelor thesis deals with the study of pyrotechnic compositions and their influence on the health and environment. It explains the nature and ingredients used in pyrotechnic compositions. During burning these compositions release different compounds, toxic or non-toxic into the atmosphere in large quantities. In this work the issue of toxicity of selected alkali, alkaline earth metals and the other harmful metals was explored. The pyrotechnic compositions containing Ba, As, Pb and Cd were investigated in more detail. When burning the pyrotechnic compositions release noxious substances into the air first. Then these substances reach due to wet or dry transport mechanism the other components of the environment and mix with them. These compounds have diverse negative effects both on humans and the environment and other animals.

Švestková, Lucie ; Novotná, Marta (referee) ; Beranová, Michaela (advisor)
The thesis evaluates the current state of environmental taxation based on CO2 emissions and determines the impact on a company ABC, s r.o. The initial section, Literature Review, discusses environmental economics and environmental policy concepts and introduces taxation procedures of road tax in Czech Republic and Ireland. The main body describes operation of the chosen company and shows real tax calculations according to the tax law of the Czech Republic and Ireland. Finally, it is discussed the potential impact on the chosen business.

Chromium and chromium species cycle in environment
Nevrlá, Jana ; Sommer, Lumír (referee) ; Dočekalová, Hana (advisor)
This work focuses in the first theoretical part mainly on the possibility of entering various forms of chromium into the environment, their accumulation and transformation in environmental compartments. There are also described methods of sampling for analytical determination of chromium, the type of treatment of these samples and the most analytical methodologies for the determination of chromium in the oxidation stage III and VI. The experimental part is focused on the quantitative determination of Cr(III) and Cr(VI) in waste water, taken from the neutralizatoin station of the Chemical faculty of Brno University of Technology, by using selected spectrophotometric methods and the obtained results are compared with the results of analytical determination of total chromium by atomic absorption spectrometry.

Effect of Business Activity on the Environment
Pustka, Ondřej ; Ing.Daniel Borski,Ph.D (referee) ; Kocmanová, Alena (advisor)
In my thesis I try to review general affect of business on the environment. Thesis focuses on available resources focused on protection of the environment, mainly those connected with waste management. The case study of Nehlsen Třinec, s.r.o. company is the part of thesis as well. It results in suggestion of improvement of investment in the company. Detailed analysis of the company is a base of this study.
